[Plugin: Contact Form 7] Not workin in Firefox

I have the contact form on several pages of my blog. When I try to fill it out and submit on IE its fine, On firefox it doesn’t ever send, just sits and spins the arrows forever.

I have tried two computers. And it doesn’t seem to matter which of the different contact forms I use, they all do the same thing.
